It's hard to keep track of who's who (and who's dead) in al Qaeda without a scorecard. Need one? Well, here ya go.

Hat tip to StrategyPage, which sums things up like this:

Short version, al-Qaeda is on the run throughout most of the globe. Even Abu Musab Zarqawi, in charge of all al-Qaeda elements in Iraq, is on the run – as elements of his infrastructure are taken apart. Eight of Zarqawi’s top aides are dead. Twenty others have been captured. Zarqawi was unable to disrupt the elections on January 30, a serious loss for the terrorists. Al-Qaeda is still potent, as the attacks in Madrid proved, but they are clearly reacting to the multi-pronged offensive in the United States.

Shorter version: The reacting side loses to the side with the initiative.
